[solved] nvidia 302.17 driver crash while playing game

[micsas]

I'v UP5 my system today. Nvidia non-free drivers were updated from 295.xx to 302.17ver. My system become unstable while playing some simple game (teeworlds). It crashes after several minutes of playing. I can see nothing in logs that could be related to my problem. I remember that the same thing was on Debian Wheezy and Fedora 17 which i tested like a month ago. I'm sure both of this distros used nvidia 302.xx drivers back then. Thus that i believe my problem is about nvidia.

How can i rollback to previous nvidia drivers?
Edit 24.09.2012
I downgraded nvidia binary drivers.
Here is what to do if u want rollback nvidia drivers.

• Find and download appropriate drivers form nvidia site i used NVIDIA 295.75
• Do the .run file executable
  

  Code: Select all

  chmod +x NVIDIA-Linux-....run

• Switch to the console CTRL+ALT+F1
• Log in
• stop window menager
  

  Code: Select all

  /etc/init.d/mdm stop

• Remove current nvidia drivers.
  

  Code: Select all

  sudo aptitude purge nvidia~i

• Execute NVIDIA instalation script.
  

  Code: Select all

  sudo ./NVIDIA-Linux-x86_64-295.75.run

If the script says that u have difrent version of gcc execute command:

Code: Select all

export CC=gcc-4.x

where x stands for appropriate version.
I run into the problem with /tmp directory being to small. Its because /tmp directory is set as a ramdisk and its size is limited. In my case it was 210MB which was not good enough. I have set "RAMTMP=no" option at "/etc/default/rcS" which disable using ramdisk for /tmp.
